July 2004 www.DataSheet4U.com SCAN921260 X6 1:10 Deserializer with IEEE 1149.1 (JTAG) and at-speed BIST SCAN921260 X6 1:10 Deserializer with IEEE 1149.1 (JTAG) and at-speed BIST General Description The SCAN921260 integrates six deserializer devices into a single chip. The SCAN921260 can simultaneously deserialize up to six data streams that have been serialized by the National Semiconductor SCAN921023 Bus LVDS serializer. The device also includes a seventh serial input channel that serves as a redundant input. Each deserializer block in the SCAN921260 operates independently with its own clock recovery circuitry and lockdetect signaling. The SCAN921260 uses a single +3.3V power supply with an estimated power dissipation of 1.2W at 3.3V with a PRBS-15 pattern. Refer to the Connection Diagrams for packaging information.
